MR imaging utilizing the time of flight effect |
摘要 |
Time-Of-Flight (TOF) MRI techniques are used to enhance blood flows into one of a pair of images for a given plane or slice of a patent's body. Arithmetic subtraction of such images produces a resultant image of substantially only blood flows since images of fat or other tissue are thus nulled out of the resultant image. All basic MRI sequences (e.g., FE, SE, etc.) can be used in conjunction with a pre-pulse on additional sub-sequences in a plane displaced from the objective plane to be imaged. Both arterial and venous blood flows can be imaged (separately or together in one resultant image). Color coding can be used in the resultant images to distinguish blood flow directions and/or velocities.
